IMPROVEMENT IN SHEET-METALBENDING MACHINE.

The Schedule referred to in these Letters Patent and making pan of thesame To all whom it may con-cern.-

Be it known that I, C. C. HABE, of Kansas City, in the county of Jacksonand State of Missouri, have invented anew and useful Sheet-metalbendingMachine; and I do hereby declare the following to be a descriptionthereof, reference being had to the accompanying drawings and to theletters of reference marked thereon.

The nature of lny invention consists in the construction of a machinewith which sheet metal can be bent into the various forms required forcornices of buildings and other similar work or structures, and doingthis with much more accuracy, regularity, quickness, and facility thanit can be done by hand, or by any other machines heretofore known orused.v

To enable others skilled in the art to make and use my invention, I willproceed to describe the construction and operationot' the same.

In the drawings- Y Figure l represents an elevation ofthe machine.

Figure 2, an end elevation, partly iu section.

Figure 3, a transverse section, and in part an elevation.

Figure 4, details of the machine.

No. l, of tig. 4, shows the method of bending the sheet over n thecurved former,

No. 2, shows another form of mold; and

No. 3, the plan ofthe ends of the machine, showing the journals andbearings of the anule anches, i

C and the adj listing-screws.

Ais the upper-anched matrix, and A', the lower or bed-anehed matrix. BB', the brace-rods or hog-chains for trussing the -anch'ed matrices. y

G C, the side pieces at the ends lsupporting the shaft E and the bearingG, and through which the set-screws e2 and q are worked.

D D, the wooden frame, in which the machine is supported. l

E the cam-levers. F l1", the wedge-blocks, to keep down the ilnnclxedmatrix A when operating.

G G', the journal-boxes, supporting the journals of' matrix A. I

H H, the metal-bearingand frame at the ends.

I, the wooden part ot' the n'iold-tbrmer, on which.

the bended metal sheet Ii is fastened.

a a', the ianches of the matrices, at right angles to the webs A A. p

a a, the journals of the matrices. b l), struts or braces to support thehog-chains. B B' b2, the handle. y c c', the brackets, to stitfen theanches of the matrices.

d, the sheet metal to bc operated on. e, shaft or rod, to support thelanched matrix A. 01, the pendent bearing for matrix A.

e2, set-screw for adjust-ing the same.

ff are brackets on the matrix A, to support the wedges F F.

g g', the set-screw for adjusting the bed-matrix A.

The operation ot' the described machine is as follows:

The sheet of metal, represented by the -red line (l in fig. 2, isinserted between the matrices A and A.

The matrix A', by the hog-chain B' as a handle, is then raised to theposition shown in tlg. 3, and bends the sheet into the form shown by thered vline d.

Then, if it be desired. to bend the sheet into another and a curvedform, the mold-former is placed upon the lanch of matrix A', with itsmetal` plate between the matrices, and then the sheet is bent down overthe curve-former I, by hand.

Formers ot' any other desired shape may be substituted for-the former I,to form such shapes of molding as lmay be desired. f

By the peculiar construction and arrangement of these devices, a small'amount ot' force, applied by hand, becomes very ethcient.

The natrix A is held iirmly upon the sheet metal by the cam-levers EE,fo1lned as. shown in iig. 1, and which operate on'the blocks F and F',resting upon the metal frame H H and brackets ff.

It is raised and lowered by means of lever handle b2.

The matrices A and A are hung and arranged in an adjustable manner, sothat'bcth square and circular-formed moldings may be formed ot any sizesthat may be desired.

This is accomplished thus:

The journal-boxes G G' slide on the bottom of the frame H and H', and,by means of set-screws g and g',

maybe moved back and forth at will.

The matrix A is lullig on the rods e e by the bearings e' el, which aremoved back and forth by means of set-screws e'2 e?.

What I claim as new, and desire to secure by Letters Patent, isv 1. Thependent bearings el el, set-screws e? c?, side pieces C C and C' Of,bars c e, and matrix A, when constructed and arranged asy described.l

' 2. lhe described 1nold-ibrmer I, with the matrices A and A', and theiradjustable bearings, respectively, and their other parts with thecam-levers E E', and the metal bearings H H, when combined and arrangedas described.

3. rIhe described .matrices A and A', wit-h their rcspective journals,hog-chains, struts, and brackets, the cam-levers E and E', with thependent bearings el e, set-screws et e, side pieces C C and C C', andbars e c, when constructed and arranged as described.
